If the blade is suspect, but replacing it is not currently an option, the blade lead can be temporarily compensated for by skewing the fence:

1.Cut a scrap piece of wood about the same length as the band saw table, and joint one edge along its length, or rip it on a table saw to give it a straight edge.

2.Draw a line on the board parallel with the jointed, or straight edge of the board.

3.Move the band saw fence out of the way, and carefully make a freehand cut along your drawn line on the board. Stop about midway on the board, and shut off the band saw (allow blade to come to a complete stop) but do not allow the board to move.

4.Clamp the board to the table.

5.Slide the band saw fence over against the board until it contacts the straight edge of the board at some point. Lock the fence down.

6.Use the back adjustment screws (F, Figure 13) to line up fence against board.

NOTE: Skewing the fence to correct blade lead is effective for that particular blade; when a new blade is installed, the fence will need re-adjustment and re-squaring to miter slot. See appropriate sections in this manual.

11.0Maintenance

Before doing maintenance on the machine, disconnect it from electrical supply by pulling out plug or switching off main switch! Failure to comply may cause serious injury.

Clean band saw regularly to remove any resinous deposits and sawdust.

Keep miter slot, and guide bearings, clean and free of resin.

Keep blade clean and sharp. Check it periodically for cracks or other signs of wear.

The drive belt should be checked periodically. If it looks worn, frayed, glazed or otherwise damaged, replace it.

Remove any deposits from band wheels to avoid vibration and potential blade breakage.

Vacuum or blow out dust from inside cabinet. (Use proper dust mask equipment).

The table surface must be kept clean and free of rust for best results. If rust appears, it can often be removed with a mixture of household ammonia, good commercial detergent and #000 steel wool. Alternatively, commercial rust removers can be found at many hardware stores.

Apply a light coat of paste wax to table. There are also products in aerosol form available in major hardware stores and supply catalogs. Whatever method is chosen, the coating should protect the metal and provide a smooth surface, without staining workpieces.

If the power cord is worn, cut, or damaged in any way, have it replaced immediately.

11.1Lubrication Points

1.Periodically apply a light, non-hardening grease to rack and pinion system of guide post (Figure 43).

Figure 43

2.Grease the sliding surfaces of the table trunnions (Figure 44).
